PAIN'JJ-BRUSH.

Application led April 4, 1916. Serial No. 88,867'.

7 'o all 107mm it may Concern.'

Be it known that I, WiLLIAM MOINTYRE RAEBURN, a subject of the King ofGreat Britain, resident at Toronto, in the Province of Ontario, Canada,have invented certain new and useful Improvements in Paint- Brushes, ofwhich the following is a specification. t

My invention relates to improvements 1n paint brushes, and moreespecially to brushes in which a paint container or reservoir isprovided.

My invention is particularly useful to scaffold workers andSteeple-jacksas it obviates the necessity of carrying a paint pot; andfor ordinary work it saves the user from constant stooping in order todip -his brush in the paint and thus, incidentally, it saves any loss ofpaint between the pot and the work. The user also in working with thebrush keeps the paint constantly stirred.

It will be found that if the valvebe kept open when the brush is to beused for ceiling or overhead work any paint which would ordinarily rundown the brush on to the operators hand now flows back through the valveinto the paint reservoir.

I am well aware that brushes somewhat along the lines of my inventionhave previously been made, but in those brushes the means forcontrolling the flow of paint from the reservoir is imperfect and thebrush head at times becomes overfull of paint; no means is provided fordistributing the paint through the bristles; and specially constructedbrush heads are required.

Now in the present invention the valve between the paint reservoir andthe brush head which may be arranged either above or below the valveseat, is controlled within certain limits as to its travel by a springand also by a disk attached to the said spring. When the valve is openedbeyond a certain extent the disk above referred to tends to restrict theflow of paint so that the brush head will. not be flooded with paint. Adistributing disk is arranged in the upper part of the brush head closeup under the pipe connecting the reservoir with the said brush head. Bymeans of this disk the paint is evenly distributed throughout all thebristles of the brush. The paint reservoir is so designed that it may beattached to an ordinary brush head: all that is required is a thread orother securing means Specification of Letters Patent.

for attaching it to the reservoir, and the center of the brush head mustbe bored and provided with a hollow plug, which can always be readilydone as it is well known in the artthat no bristles are arranged in thecenter of brushes.

With these and other objects in view my invention consistsin certainnovel construction and combination of parts hereinafter more fullydescribed with the aid of the accompanying drawings, in which similarparts are similarly designated in all the views, and claimed.

VMoreover it is understood that I may make alterations and modificationsprovided the said alterations and modifications fall within the scope ofwhat I claim.

Figure l is a sectional elevation of my brush.

Fig. 2 shows a modified form of my valve arrangement.

Fig. 3 is a plan of the valve shown in Fig. 2; in this case thedistributing disk is formed by the underside of the valve.

Fig. 4 is a'detail of the distributing disk used in the arrangementshown in Fig. l.

Now referring more particularly to the drawings, l designates areservoir provided at its upper end with a removable cap 2 which iseither screwed on to the said reservoir l or held thereon by othersuitable means. A handle 3 is rigidly attached to the upper side of thesaid cap 2.

A brush head 4 is screwed or otherwise secured to the lower end of thereservoir l. The means employed for fastening the brush head should beone which would permit of the easy removal of the brush, so that anothermay be quickly substituted when the bristles become worn out.

In the brush head 4 and substantially in the center thereof I provide ahole 5 through which I insert a hollow plug or tube 6.

In the arrangement shown in Fig. l a valve seat 7 is arranged on theupper side of the tube 6 on which the valve 8 rests. The said valve 8 ismounted on the connecting rod 9, the lower end of which is secured tothe distributing disk 10 which latter is'held in its lowest position bymeans of the spring 11 which is fastened both to the distributing disk10 and to the lower end of the tube 6.

In the modied arrangement shown in Figs. 3 and 4 the valve seat 7a isprovided on the underside of the tube 6 and the valve 8a is held inposition by means of the spring 11a arranged between the base of thereservoir 1 and the underside of the plate 12. In this form ofconstruction it will be noted that the valve Sa is secured to the lowerend of the connecting rod 9a and also that the distributing disk 10a isattached to the underside of and integral with the said valve 8u.

The connecting rod 9 or 9a is secured at its upper end to any suitableform of operating arm 13, by means of which the valve 8 or 8 is openedand the paint allowed to pass into the brush head when it is evenlydistributed in all directions among the bristles by the notches in thedislrlO or 10a.

What I claim as my invention and desire to secure by Letters Patent is:

1. A paint brush comprising a handle, a brush head, a reservoir arrangedthereon, a tube in the top of said brush head provided .with a valveseat and a valve attached to a connecting rod operated by an arm .'ar-

ranged through lthe side of said brush Copies of this patent may beobtained for tube in the top of said brush head provided with a valveseat and a valve attached to a connecting rod operated by an armarranged through the side of said brush handle, in combination with aspring adapted to hold said valve in closed position, a distributingdevice carried by said connecting rod, and means provided in said handlefor retaining the valve in open position so that paint may flow backinto the reservoir when the brush is being used for overhead Work.

3. A paint brush comprisingra handle secured to the upper side of aremovable cap, which latter is mounted on a reservoir connected to abrush head by a hollow tube provided with a valve seat, in combinationwith a connecting rod having an operating arm arranged through the brushhandle, a valve mounted on said connecting rod which latter' terminatesin a notched distributing disk, said valve being held in closed positionby means of a spring arranged around said connecting rod, and meansprovided in said handle for retaining the valve in open position.
